To all whom it ptay c0n0ern.-

Be it known that I, BERNHARD C. J. ANDER- SON, a citizen of the United States, residing at Morton Park, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Gas-Generators,of which the following is a specification.

My invention relates particularly to an imdesired height for consumption,thus enabling comparatively low-grade inexpensive oils to be used, with consequent great saving of expense. I accomplish the desired results by means of the improved generator illustrated in the accompanying drawings. The generator comprises, generally stated, an elevated oil-chamber which may be recharged from any suitable oil-reservoir, a discharge-pipe, preferably of upright U -shape form, communicating with said oil-chamber, a generatorburner toward the lower end ofthc rising portion of said U-shaped pipe, provided with a chimney inclosing said rising portion of the pipe, a pipe leading from the upper portion of said oil-chamber to said burner and serving to cond uctfumes arising from the oil, and also generated gas, to said burner, and a service-pipe communicating with saidrising portion of the U-shaped pipe, preferably supplied with means for mixing air with the gas before the service-burner is reached and with means for collecting any oil or impurities carried over with the gas or any condensation from the gas itself and returning the collected oil to the oil-chamber.

In the accompanying drawings, Figure 1 is a View in elevation and diagrammatic in its nature, showing my improved generator and its manner of installation; Fig. 2, a broken vertical section of the upper portion of the device, the section being taken on line 2 of Fig. 6; Fig. 3, an enlarged sectional detail of a needle-valve regulating the passage of gas from the generating-pipe toward the servicepipe, the section being taken at line 3 of Fig. 6; Fig. 4, a sectional detail of a valve regulating the passage of fumes and generated gas from the oil-chamber to the generator-burner, the section being taken on line 401: Fig. 6; Fig. 5, a plan section of the rising portion of the generator-pipe and the pipe-like chimney inclosing the same; Fig. 6, a general top plan sectional view taken as indicated at line 6 of Fig. 2; Fig. 7, a broken detail of the pump employed for filling the oil-chamber, and Fig. 8 a detail of the generator-burner.

A represents an oil-chamber conveniently supported on a hollow standard B, through which passes the descending portion 25 of a U shaped pipe C in communication with the lower part of the chamber A. The rising portion i of the pipe 0 is by preference incased in a pipe D, serving as a chimney foragenerator-pipe heater or burner E, supplied with a combustion-chamber E, inclosing the lower portion of the pipe 15.

The burner E is supplied with a perforated burner-plate E and beneath said plate with a fuel-supply pipe F, communicating with the chamber A above the oil-line. In the course of the pipe F is placed a needle-Valve F, Fig.-

4, adjusted by means of a pivotally-secured handle F moving on a dial-plate F supplied with notches s for the reception of a lug s on said handle. The pipe F is supplied below the valve with air-inlets a", and preferably extends below its point of communication with the burner, as shown, to aid in the production of a strong updraft through the burner at the instant of ignition. The combustionchamber is supplied above the burner-plate with a door q, pivoted at its upper portion, and preferably also with apertures q, guarded by wire-gauze g The upper end of the pipe t is joined to a valve-shell G, Fig. 3, supplied with a needlevalve G, operated by a hand-wheel G and is also supplied with an indeX-pointerp, which has feather-and-groove connection with the spindle of the valve and is spring-held in contact with a dial G supported from the shell G. The shell Ghas screw connection with a perforated plug H, which in turn screws ad-' justably into the end of a pipe H, disposed above and supported by the chamber A.

Within the pipe H and located in close proximity to the port guarded by the valve G is a short pipe I, which has gas-tight connection with an annular ring a on the interior of the pipe H. Into the pipe I the gas issuing from the port at the valve G passes with sufiicient velocity to induce an air-current through a pipe J, leading from the adjacent part of the pipe H to the exterior of the wall K of the building in which the generator is installed. The intake end of the pipe J is shown protected by a hood J. A small drain-pipe m, having gas-tight connection with the pipe H, adjacent to the valve G, and with the top of the chamber A and extending to near the bottom of the chamber A, serves as a sealed return-channel to the chamber A for any particles of oil collecting at this point which may be carried through at the valve G.

Beyond the pipe I the pipe H has connection through a pipe L with the upper part of the chamber A, From the pipe H the gas passes to a service-pipe M and any desired number of service lighting or heating burners M through an interposed trap-supplied collecting device P. The device P comprises, preferably, an elbow-joint l, supplied with a trap l and with an inner passage Z leading to a relatively short pipe which projects upward from a diaphragm Z, and an enlarged pipe Z which screws into the upturned portion of the elbow. A drain-pipe Z extends from the diaphragm Z to near the bottom of the trap Z, and the passage Z is in communication with the trap l through a passage Z By this arrangement, it will he observed, the channel for the passage of gas is through the chamber Z and pipe 1, the pipe Z being sealed by the first collection of liquid in the trap.

)Vhen service-burners suflicientto consume all the gas which is being generated are simultaneously in use, there is comparatively little condensation of gas within the system, the trap Z serving then merely to collect any water or otherimpurities present. If a number of the service-burners are thrown out of use while the machine is generating gas at its full capacity, however, the sluggish movement of the gas, with consequent opportunity for cooling, causes a larger condensation. In such case the condensed liquid fills the trap l, the water and other impurities settling to the bottom, where they are drawn off from time to time,and the oil rising through the opening Z and returning through the pipe H to the chamber A.

The gasolene may be stored in a tank N outside the building and raised to the chamber or head A through a pipe k by means of a pump N. The pump is shown in detail in Fig. 7 and is of a well-known construct-ion. An overflow-pipe h, communicating with the chamber A a short distance below its top, prevents the oil-level from rising above the dotted line h. (Shown in Fig. 2.)

The operation is as follows: A supply of oil is raised to the chamber A by means of the pump N, the agitation of the liquid being sufficient to cause fumes to pass through the pipe F and open valve F and descend to the burner E, where they may be ignited through the door q. As the generating pipe or chamber t becomes heated (supposing now the valve G to be closed) gas collects in that portion of said pipe above the oil-level and gradually forces the oil back out of the generator portion of the U-shaped pipe. The liquid column in the pipe 25 is now balanced by gaspressure in the pipe t, and if the valve G be opened the gas will shoot through the pipe I and induce an air-current through the pipe J suflicient in volume to supply the desired quantity of oxygen. The gas will now rise in the pipe M (if unimpeded) till the gas column is of suflicient height to balance the liquid column or head in the pipe 25 and chamber A, it being borne in mind, of course, that the reduced orifice at the valve G acts virtually as a pressure-reducing valve. In practice the liquid column is of suflicien t height and the burner E sufficiently low to force the gas to a plane above the service-burners, thus insuring pressure at the burners.

As indicated in Fig. 3 and as stated above, the fuel -supply pipe F of the generatorburner E is in communication with the oilchamber A above the oil-level, whence it receives a supply of gas as soon as the pipe H is put into communication with the genera tor-pipe i, since the pipe II is in communication, through the medium of the pipe L, with the upper portion of the chamber A.

If the number of service-burners in use corresponds exactly to the capacity of the machine, but small condensation occurs. If, however, fewer burners are in use than will consume the gas being generated, there will be a condensation of the gas in the upper pipes and a return of the gasolene through the channel described to the liquid source or head.

It will be observed that the portion of the apparatus in which the gasolene moves as a liquid is closed, the service-burners being located above the highest possible point reached by the liquid (under the established head or pressure) on a service-pipe constituting, in effect, an extension of the generator-pipe. The location of the generator-burner should be at a sufficient distance below the oil-level (capable of being reached in the generatorpipe when the generator-heater is unlighted) to produce such inequality in pressure between the gas and liquid columns as that the gas will be raised to the desired height and caused to issue at the desired'pressure at the service-burner.

WVhile it is believed to be greatly preferable to use the oil column itself for furnishing the pressure of controllable maximum which is depended upon for insuring perfect safety in the use of the machine, yet it is deemed within the spirit of my invention to use other pressure (such as pneumatic) of predetermined maximum for accomplishing the same result. Thus the lower portion of the descending pipe t is to be regarded as an oilpressure chamber for supplyingadeterminate pressure to the fluid in the generator-pipe t capable of supporting in the pipe it an oil column of a given height, the pipe i being without communication with the external atmosphere to a plane above that to which the oil can possibly rise under the pressure supplied, thereby removing danger of escape of oil from confinement except as a gas. The pressure means shown is that portion of the apparatus containing the descending oil column-t'. 6., the oil column above the generator-burner E on the feed side of the machine. Said oil column may be removed and means for supplying pneumatic pressure provided. This is what would occur were the chamber A lowered beneath the level of the burner E and air-pressure supplied. Were the chamber A lowered, so as to preserve a certain head above the burner E, and pneumatic pressure then supplied, it is evident that both liquid and pneumatic pressure would then be used for producing the required gas-pressure.
